Betsy DeVos: "We simply cannot allow this trend to continue"

Secretary of Education Betsy DeVos just issued a statement on the shooting at Santa Fe High School.

In it, she said schools must be "safe and nurturing environments" and "we simply cannot allow this trend to continue."

Here's her full statement:

My heart is heavy from watching the horrific events that unfolded at Santa Fe High School today. My prayers are with each student, parent, educator and first responder impacted. Our schools must be safe and nurturing environments for learning. No student should have to experience the trauma suffered by so many today and in similar events prior. We simply cannot allow this trend to continue. 

Every day, the Federal Commission on School Safety is working to identify proven ways to prevent violence and keep our students safe at school. Our work remains urgent. Our nation must come together and address the underlying issues that lead to such tragic and senseless loss of life.

Santa Fe students said "#NeverAgain" in April's school walkout against gun violence

Students at Santa Fe High School participated in the national school walkout against gun violence on April 20, according to photos tweeted by one of the students.

In those photos, Santa Fe students can be seen holding a poster that says "never again" and are gathered in a small circle outside the school.

The student that tweeted the images said, "We read a poem by a parkland survivor, handed out gun violence fact sheets and orange ribbon, did 17 minutes of silence, and then talked about ways to raise awareness for gun violence, and make your voice heard."

We've reached out for comment from the student and will share more if we hear back.
